DOD DFX5 Digital Turbo Distortion

a 1990 DOD brochure

The DFX5 Digital Turbo Distortion delivers distortion and singing sustain that simulate an amplifier cranked to ten. And, to fatten the sound, the DFX5 has variable digital delay. With 12-bit processing, 90dB S/N, and a 20Hz to 20kHz bandwith, the DFX5 is a superb effect pedal.
